These are some really nice behind the scenes photos that show off different alien makeup designs created for Guardians of the Galaxy. You have to love the retro look and feel of this movie and admire all of the practical effects that were used to pull it off. These designs have so much detail!
Dave White, the special effects makeup designer helped to create the designs for Gamora, Drax, Nebula, Yondu, Korath, and other aliens. They are all done practically and are free from modern alien design influences. The end results in the film were simply amazing. You’ll find more at the link.
